C＃| CharEnumerator.MoveNext()方法

CharEnumerator.MoveNext()方法用于将当前CharEnumerator对象的内部索引增加到枚举字符串的下一个字符。

句法：

public bool MoveNext();

返回值：该方法返回布尔值true值，如果索引成功递增，并列举字符串否则为false内。

下面的程序说明了CharEnumerator.MoveNext()方法的用法：

范例1：

// C# program to illustrate the
// use of CharEnumerator.MoveNext()
// Method
using System;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "A Computer Science Portal for Geeks!";
  
        // Instantiate a CharEnumerator object
        CharEnumerator chEnum = str.GetEnumerator();
  
        // Printing the string
        while (chEnum.MoveNext()) 
        {
            Console.Write(chEnum.Current);
        }
    }
}

输出：

A Computer Science Portal for Geeks!

范例2：

// C# program to illustrate the
// use of CharEnumerator.MoveNext()
// Method
using System;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
        // Initialize a string object
        string str = "Best Data Structure and Algorithms Tutorials!";
  
        // Instantiate a CharEnumerator object
        CharEnumerator chEnum = str.GetEnumerator();
  
        // Printing the string
        while (chEnum.MoveNext()) 
        {
            if (chEnum.Current == ' ') 
            {
                Console.WriteLine();
                continue;
            }
            Console.Write(chEnum.Current);
        }
    }
}

输出：
